ABSTRACT:
This distribution transformer is of the shell type and includes within its oil-filled tank a layer-type high voltage winding and a layer-type low voltage winding. The low voltage winding is divided into two sections with a grounded interconnection between said two sections. A metal oxide varistor device is mounted within the oil-filled tank and is connected between the high voltage terminal of the high voltage winding and ground. There is another connection between the mid-point of the varistor device and the mid-point of the high voltage winding. The varistor device so connected protects the high voltage winding against both voltage surges entering via its terminals and current surges entering via the terminals of the low voltage winding.
